A young man who "died" at least three times and was brought back to life has warned boy racers not to use Pembrokeshire roads as speed tracks.

Doctors and nurses at Morriston Hospital described 22-year-old Nicky Butcher as a "miracle boy" after he survived horrific injuries in a crash on the Haverfordwest to Broad Haven Road last June.

Nicky's skull was completely crushed. He now has 27 titanium plates in his face and head.

He has lost the sight in his left eye and hearing in his left ear. He cannot smell because he has no sinuses.

His spine was fractured and he suffered brain injury and brain damage.

The top and bottom of his jaw were split in two and the right side of his face was pushed four inches into the left side of his brain.

Nicky, now of Pontypridd, was one of five young people seriously injured in the crash.

He spent three weeks on a life support system and was in Morriston Hospital for three months.

The crash happened when he was driving back to Broad Haven with three passengers including his then girlfriend.

"I was confronted by two cars, one on my side of the road, coming around the corner. It was heading straight for me and there was nothing I could do," he said.

The crash was inevitable and Nicky was left fighting for his life.

"I would appeal to young drivers and so-called boy racers, do not race on the roads. Stick to proper racing tracks. Their own and other people's lives are at stake. I'm lucky to be here but I will have to live with my injuries for the rest of my life."

Inspector Nigel Hayes, of the Pembrokeshire Roads Policing Unit, also urged young drivers to learn from the accident and drive safely.

He and other officers who arrived at the scene of the accident were amazed no-one had been killed.

Another of those seriously hurt in the crash - driver Mark Edward Hooper, also 22, of Stepney Terrace, Haverfordwest - was sentenced at Swansea Crown Court on Thursday for dangerous driving.
